Can anyone please help I am struggling with math and Noone wants to help me and I want to learn so does anyone understand HOW u factor this

Step-by-step explanation:

256 = 16×16=4×4×4×4 = 4^4

X^4-4^4 = (x^2)^2 - (4^2)^2

Using algebraic identity a^2-b^2 = (a+b)(a-b)

We get (x^2+4^2)(x^2-4^2)

(x^2+4^2)(x+2)(x-2)

Crop yield is the ratio of the number of bushels harvested to the number of acres used for the harvest. This year, a large farm harvested rice from 690 acres of farmland. The crop yield was 7,553 bushels per acre.

Approximately how many bushels of rice were harvested?

0.1 million bushels

5.2 million bushels

8.2 million bushels

10.9 million bushels
